Authenticated service interruption via download data-collection overflow
Published Mar 27, 2026 · Updated Mar 27, 2026
Stack-based buffer overflow in affected Softing industrial gateways allows remote authenticated users to interrupt service. The data-collection path used to prepare downloads writes beyond a stack buffer, but Softing has not disclosed the responsible request or routine. Network access with low privileges is required, and the published impact is limited to availability rather than data access or modification.
